Zika virus: What you need to know

The recent outbreak of the Zika virus in certain parts of the world has many mothers-to-be wondering if they’re at risk — and how they can protect themselves during pregnancy. Whether you’re looking for facts and details or just want some piece of mind, here’s what you need to know about the virus.

What is the Zika virus?

The Zika virus is an infectious disease that’s linked to birth defects. While the virus doesn’t cause serious problems for most people who get it, it may be very dangerous for unborn children. If a pregnant woman gets the virus, it may cause birth defects in her baby, including a smaller-than-normal head and certain developmental problems.

How does Zika spread?

The Zika virus spreads mainly through bites from infected mosquitoes. It can also spread through sexual contact, and, very rarely, through blood transfusions.

Where is Zika spreading?

As of August 18, 2016, the outbreak is most active in Mexico, Central and South America, Puerto Rico and the Caribbean, some of the Pacific Islands, and parts of Florida. However, the situation is changing quickly.
